Encoder Failure
Likely causes
- Damaged encoder
- Loose coupling
- Wiring fault
- Contamination
How to fix it
- 1Stop the machine.
- 2Inspect the encoder and its coupling.
- 3Check electrical connections.
- 4Clean the encoder if contaminated; replace if faulty.
- 5Verify machine positioning before production.
It is fixed when
Position feedback is stable and accurate.
Stop it coming back
- Inspect encoder mounting and wiring during preventive maintenance.
